Gentlefolk,
I added a pointer to the shaft of the motor (like a clock hand) so I
could see what the motor was doing.
I then set the current and acceleration values.
I then ran a series of tests at various steps/rev and fiddled the
velocity until I could get stable performance (consistent counts, no
erratic jumping, return to the initial count, etc).
The following table shows the results, these are the maximum velocities
for stable performance.
Current 0.5A for all tests (emperical and from one vague reference in
the Internet )
Accelleration
10MM/S^2 for all tests
Step/rev 50 100 200
Max Velocity 2.9 1.7 0.9
MM/S
So it looks like I have a 200 step motor...........
